Title: Method for sealing underground formations, particularly in the field of oil drilling, as well as corresponding applications and compositions
Inventor: OBERSTE-PADTBERG RUDIGER
IPC: E21B33/138
Filed: 1986-11-25
Abstract: The invention relates to a new method for sealing and/or consolidating a permeable geological formation, particularly one passed through by a drilling well. The method according to the invention includes the following stages: a) insertion into the formation Z of an over-retarded gel composition GR comprising a gelling compound and a hardening agent, the setting time of which is much greater than the time for proper positioning of the composition, so that the latter runs into the formation from the well and over a notable distance, b) injection, behind a mechanical or fluid stopper, of a rapid-action gelling agent 1 so as to gel instantaneously the part of the over-retarded gel composition located in the immediate vicinity of the interface of the zone to be treated and of the drilling well, which stops the over-retarded gel composition from moving towards the inside of the formation. A gel is obtained which is strong and placed correctly. Application to the treatments of oil, gas, water and geothermal wells.

Title: Digital pulse compression method for measuring distance separating radar and e.g. aircraft, involves developing phase code with phase values varying based on quadratic law, and emitting pulses whose phase varies based on phase code
Inventor: PLESSZ ERIC
IPC: G01S13/00
Filed: 1987-08-18
Abstract: The method involves developing a phase code, in digital form, comprising specific phase values varying based on a quadratic law. High frequency pulses (20-26), whose phase varies based on the phase code, are emitted, and signals acquired in response to the emitted pulses are received. Phase and amplitude of the signals are extracted, and the extracted signals adapted to emitted pulse duration are filtered. The extracted and filtered signals are sampled and coded for obtaining the code in digital form in a remote case where a signal is present, and the code is calculated from Fourier transform. An independent claim is also included for a radar for implementing a digital pulse compression method.
